Synthesis and researching of the structure and mechanical properties of a metal-matrix composite material based on aluminum hardened with basalt fibers

This paper investigates the effect of basalt fibers on the physical and mechanical proper-ties of the aluminum alloy A356. It was found that with the introduction of 1.5 wt.% Basalt fibers, the microhardness increases from 68 HV to 82 HV, the width of the eutectic decreases from 12 to 7.5 μm
